IMPROVEMENT IN SEAMS FOR BOOTS AND SHOES.

Specification forming part of Letters PatentNo. 133,826,'dated December 10, 1872.

, of which the following is a specification:

Our invention relatesto the method of forming the seams in sewing together the parts composing the uppers of -boots and shoes; and consists in stitching together from the outside the two parts to be joined, with or without an interposedjwelt, in such manner that the edge of the one part shall extend so far beyond the line of stitching that it may be turned over the edge of the other part and againstitched beyond the edge thus c'overed to the main body of: such other part. The edge thus covered over raises a ridge between the two-lines of stitching that serves to protect the stitches from attrition in wear; and this ridge may be .made more prominentby inserting a small cord under the edge to be turned over before When, however, the leather is thick enough the ridge will have suflicient prominence without theuse of such cord. Preferably, the edge to. be turned over and sewed down over and beyond the other edge is made to extend further beyond the irst line of stitching than the other edge, but when this is not the case the edge to be covered must be rolled or folded back so that the other edge can be lapped entirely over and sewed down beyond it.

Our invention is applicable to the joining together of the parts of a boot-leg, and also the other parts of the uppers of boots and shoes; and the objects of our invention are to make a durable union of the parts with only two lines of stitchin g, t0 save turning the bootleg when it is completed, and to protect the seam-threads from attrition in wear.

Description of the Accompanying Drawing.

Figure 1 shows two pieces of leather with their inside surfaces placed together in proper position, and united by stitching them through and through, with the overlapping edge a of one piece stitched down over and beyond the edge of the other. b is the first and cthe second line of stitching. Fig. 2 shows the same before the overlapping edge a has been stitched down. Fig. 3 is a sectional view with the overlapping edge a stitched down and the small cord d inserted to make more Aprominent the ridge c between the lines of stitches.

We claim as our inventionu In a boot or shoe, the seam vformed by stitching together, from the outside, the two,

parts to be joined, and then turning the edge of the one part over and stitching it down beyond the edge and to the main body ofthe other part, substantially as and for the purposes hereinbefore set forth.
